Yes , the new tankers are double hulled, and better tended and equipped …BUT there’s been no independent risk assessment science that supports this great increase of dilbit laden tankers in these ‘chosen’ busy ,commercially lucrative waters….Pipelines and tankers, typically, fail because of ‘human error’ leaving us with just one common sense approach…and that is to minimize the probability of a tanker spill incident.., thus the newly ‘promised science’ is welcomed…hopefully , not too late ?
